								<h2>Description</h2>
								<p>Both castle and ball are simulated using MPM. The gravity is downgraded to one-tenth so that the ball can strike out the castle before landing. In this case, we modify the parameters of particles to make them powderier and less sticky. We can see that the castle collapses after the strong impact of the ball, and the particles disperse until hitting the boundaries.</p>
